Weeds mean Decisions

In a sense, farming might be called a warfare againstweeds. Some farmers emerge from the struggle victorious,while others go down to defeat. So powerful are weedenemies in reducing crop yields, while at the same timemultiplying labor,

that the farmer should at every turnstrengthen his position against them.He should bearthese invaders in mind in planning the crops he will growand in deciding on the fields where he will grow thesecrops, in choosing the implements he will use, in buyinghis seed, and in many other farm activities…Some men donot attack weeds with enough vigor; they look for rocking-chair methods of work. There is no royal road to weedcontrol. In the main, the old doctrine of“hard work andplenty of it” must be observed, but unless this work isapplied intelligently a vast amount of labor may beexpended with but little accomplishedother than atemporary abatement of the evil.

•Short term market oriented farmers grow more cropswith less competitive qualities such as flower bulbs,onions, sunflower, pumpkin, but with higher yield ($).

Conclusion of explorative study

The incorporation of the human dimension, in terms offarmers’ beliefs, attitudes and behavior, can lead to abetter understanding of the (organic) farmingsystems and lead to more effectivecommunicationon weedmanagement in those systems.

Dutch results within current project

•Similar to Midwest:

–Knowledge of (experience) EWM principles high

–External farm constraints are a barrier

•In addition to Midwest:

–Farmers indicate that species specific EWMrequires more experiment based EWM knowledge(knowledge research can not provide yet).
